You want to solve for x so add 18 from both sides of the equal sign. making it 3x=12. then divide both sides by 3 making x=4. x is 4.

$-18+3x=-6$

Add 18 to both sides:
$-18 +3x +18=-6+18$

$3x=12$

Divide both sides by 3:
$\frac{3x}{3} = \frac{12}{3}$

$x=4$

Therefore, x=4

If a gas-filled balloon rises 40 feet in the 1st minute, 60 feet in the 2nd minute, and 80 feet in the 3rd minute, how many feet

tresset_1 [31]

The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.

System of equations-4× 7y=-8-5× 6y=1

Anton [14]

-4x + 7y = -8 . . . (1)
-5x + 6y = 1 . . . .(2)

(1) x 5 => -20x + 35y = -40 . . . (3)
(2) x 4 => -20x + 24y = 4 . . . . .(4)

(3) - (4) => 11y = -44 => y = -44/11 = -4
From (2), -5x + 6(-4) = 1 => -5x - 24 = 1 => -5x = 1 + 24 = 25 => x = 25/-5 = -5

Therefore, x = -5, y = -4

Answer:

Step-by-step explanation:

the +4 turns into -4

6-4=2 the (+4-4 on the left would cancel out)

-2x/2 would cancel out as well

2 divided by 2 = 1
